Has anybody out there ever put a cummins 4bt into a trackmaster601?My machine gets used every year for about a month hauling freight to northern hydro camps and is pulling heavy loads and packing trails.I want to go diesel because of the torque they produce and because 90% of the freight we haul is diesel fuel which means I dont have to haul gas.The 223 ford in it now runs good but is under powered and hard to get parts for.I realy want to go diesel for what I use my machine for.
